UNITED STA HUGH nomvnLLY, (IF-LISBON, 01-110 CAR-COUPLIN G.

. To all whom it may concern:

Be it known that I, HUGH DONNELLY, a States of America, residing at Lisbon, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Car- ;Couplers and Adjusting Mechanism, of

'which the following is a specification, refe. re1'1ce being had therein to the accompanyn,{i;..tli'zi\vi11g.' I

, jlihis invention relates to ear couplers, i .l. the primary object of my invention is to -1t ovide anautomatic car coupler with positive and reliable means for holding the coupling pin in the coupler body, thereby preventing the same from becoming accidentally displaced due to the vibrations to whiclrthe coupler is subjected by rolling stock in action.

Another object of the invention isto providea carcoupler with simple and etl'ecti've means for relieving the knuckle-tongue from wear and teauwhen swinging into the iilVlt-ll the aboveand such other objects in view as may hereina't'ter appear, the 1nveution consists of the novel construction,com-

3&5: liination and arrangement of parts to be hereimi lter specifically described and then claimed. l

Reference will now be, had to the drawing: forming apart of this specification, wherein 2--- Figure 1 is an enlarged side elevation of the coupler-head. Fig. 2 is a front elevation of the same. Fig. 3 is a perspective view of a lock litter. Fig. l is a perspective view 01. a locking pin. Fig. 5 is a side elevation of the locking pin partly broken away and partly in section, showing the lock lifter pin within the locking pin. Fig. 6 is a plan view of the knuckle. Fig. 7 is a side elevation of the same. Fig. .8 is an end elevation of the knuckle. Fig. 9 is a bottom plan of two interlocking coupler-heads. The coupler head which projects from the draw-bar 8 comprises a body 9 having a pocket 10 formed therein for the tongue 11 of a knuckle 12. The knuckle 1.2 is pivotally mounted between apertured extensions 13 of the coupler body by a pivot pin 14. The pocket 1.0 communicates with. vertical rectangular openings 15 formed in the locking body for a knuckle pin 16' adapted to lock the tongue 11 of the knuckle 12 within the pocket. The openings 15 are rectangu- -knuekle to that extent as to release the Specification of Letters Patent. Patented Sept. 19, 1911. Application filed February 7,' 1910. Serial No. 542,593.

lar in cross section to receive the locking pm 16, and said pin is cut-away, as at 17, to provide clearance for the tongue 11, the cut-away portion of said pin providing a sup porting shoulder 18 and a locking shoulder 19. The supporting shoulder 18 is adapted to rest upon the inclined rib 20 of the tongue 11 and ride upon said rib as the knuckle 12 is swung open. An ope movement of the knuckle 12 is limited by 0. lug 21 at the upper end of the inclined rib 20. The locking shoulder 19 is adapted to engage the end of the rib 20, as at 22, and lock the tongue 11 within the pocket 10, thus 'n'eventing the knuckle from being openec. l

The locking pin 16 adjacent to the cul away portion 17 is provided with a bearing 23 .t'or a revoluble roller 24 which is out ployed as a movable bearing for supporting the rib 20, the roller 21 extending slightly above the surface which is indicated at X, Fig. 8. The rib 20 would rest u on the surface X if it were not for there ler 24. As the pin 16 is illustrated in perspective in Fig. 8, the roller does not appear as extending above the surface X. As the roller 21 extends above the surfaee X, there will be no friction between the rib 20 and said 5 surface as the rib moves between the latter and the shoulder 18.

The locking pin 16 above the cut-away portion 17 is provided with a vertical slot 26, the upper end of the'slot terminating at the head 27 of the lockin pin. The bottom of the slot is inclinet, as at 28, and eonunnnieating with the lower portion of the slot .36 is an angularly disposed opening" 29 in the locking pin. In the slot 26 and 95 the opening 22) is mounted a lock lifter 30 having the upper end thereof )rovided with a head 31 and an apertured ug 32, while the lower end thereof is provided with a book 33 adapted to extend into the opening 100 23) and with a protuberance Z54 alining with the book 33. 'lhe'wall ot the pocket 10 alining with the walls of the openings 15 is provided with a recess 35" adapted to receive the protuberzmce 3-4. of the lock litter 0 30 and thereby lock the locking pin 16 within the openings 15, thus preventing vibra-' tions of the rolling stock from jarring the tongue 11 ot' the knuckle.

As best shown. in Fig. 9 of the drawmgs,

the book 33 of the lock litter is in a retracted '29 until it engages the wall of the opening l5, and as it cannot further advance in the opening 29, the locking pin will be elevated. When the locking pin is elevated and the end of the opening 29 clears the upper surface of the coupler body, the hook 33 will be immediately projected and the end of the hook is so constructed as to engage the upper surface of the body and support both the lock lifter and locking pin in an elevated position. When in such position the shoulder it of the locking pin is sufiiciently ele; vated to engage the inclined rib 20 of the knuckle tongue 11. The knuckle is now in position to be swung open. For instance, if it was desired to pull one car away from the other, it would be necessary that the lock lifter and the locking pin be elevated, before the knuckle 12 could swing open. As the knuckle swings to an open posit-ion the looking pin is iurther elevated and the lock lifter recedes until the protuberance 3% enga cs the wallpf the opening 15.

assuming thatthe knuckle is in an open 1 po'sition and that another knuckle contacts with the tongue 11, the knuckle will be swung inwardly allowing the locking pin to .descend, and immediately upon'the rib 2O clearing the shoulder 18, both of the locking pins 16 and lock lifter 3O would drop into position with the shoulder 19 holding the rib 20 and the protuberance 34 of the pin 30 holding the locking pin in a locked position.

A suitable elevating mechanism can be attached to the lock lifter whereby it can be manipulated from the side of a car without a trainmaii going between to couple the cars. As an example of the elevating mechanism, I show a ivoted lever 85 upon the coupler body, said lever extending through by the coupler bodies or heads will be rigidly held after the knuckles 12 have been coupled.

What I claim is:

A car coupler comprising a coupler head, a knuckle pivotally mounted in said head, a vertically movable locking pin arranged within the head and adapted to engagevthe knuckle for retaining it in closed position, said locking pin provided with a vertically disposed slot and an angularly extending opening at the inner terminus of the slot, said coupler head provided with a recess opposing one end of said opening, a lock lifter shiftably mounted in said pinand provided with a protuberance engaging the walls of said recess for "locking the pin within the coupler head, sa.id lock lifter further provided with an angula'rly disposed hook engaged with the locking pin, and means engaging with said lock lifter. for shifting it to move the said protuberance out of said recess to release the locking pin and further adapted to shift the hook to engage the wall of the opening to elevate the pin to release the knuckle, said lock lifter adapted to have the hook thereof profiect from the pin and engage the draw head for maintaining the latter in an elevated position when raised to such position by said means.

In testimony whereof I afiix my signature in the presence of two witnesses.
